Description
Technical Field
The present invention relates to an improved version of a yarn twisting machine, which is described in publication No. WO2008036055, and in particular to such a yarn twisting machine: which includes a convenient arrangement suitable for twisting friction-sensitive yarns, such as continuous filament yarns and industrial yarns, without any damage.
Background
WO2008036055 (for a yarn twisting machine) comprises: a main shaft driven by a first motor and disposed at the center of a twisting disc (twisting disc), the main shaft having an axial opening through which a yarn to be twisted is fed; a main lower drive ring driven by the second motor and coaxially housed so that it will be located at the lower side of the twisting disk; and an upper drive ring coaxially received such that the upper drive ring will be located at an upper side of the twisting disk. The twisting disks are provided with a non-magnetic material and the lower drive ring below the twisting disks contains a plurality of magnets arranged in an annular manner. Similarly, the upper drive ring above the twisting disks is provided with a plurality of magnets fed in a ring-like manner which are aligned with the magnets on the lower drive ring but have opposite poles to the magnets of the lower drive ring. Thus, according to WO2008036055, a magnetic coupling is formed between the lower drive ring and the upper drive ring.
In WO2008036055, the energy received from the second motor is transferred by magnetic coupling to the upper drive ring and then to the yarn winding drum and by the pulley mechanism to the yarn feeder housed on the upper platform on top of the machine.
According to WO2008036055, the yarn to be twisted is fed through a hole formed along the axis (shaft axis) and then through a hole opening in the radial direction to the twisting disk. The yarn is further passed to a yarn feeder on an upper platform to form a yarn ball. The twisted yarn rubs against the rounded sides of the upper fixed platform and the resulting heat can cause damage to the yarn (depending on the type of yarn used). While friction does not damage, for example, cotton, continuous filament yarns such as nylon, polypropylene, polyester, aramid, etc. may break due to the heat of friction.
On the other hand, if the yarn to be twisted is an industrial yarn, such as glass fiber, basalt fiber, and carbon fiber, friction and the temperature rise caused by it may become critical. A similar situation occurs when the yarn is made of any metallic material (copper, silver, stainless steel, tungsten, etc.). In this case not only the friction of the twisted yarn against the circular side of the upper platform in a similar way as in WO2008036055, but also the friction caused by the contact of the yarn with the driven yarn feeder becomes crucial. For the above reasons, WO2008036055 may bring some drawbacks to twisting continuous filament yarns and industrial yarns.
Disclosure of Invention
The object of the present invention is to provide an effective twisting of a friction sensitive yarn.
To achieve the object, the present invention relates to a yarn twisting machine including: a spindle into which one or more yarns are introduced and from which one or more yarns are withdrawn, the spindle being driven by a first motor; a lower twisting disk in contact with one or more yarns taken out of the main shaft and associated with said main shaft (in communication); an upper twisting disk having an opening through which one or more yarns forming a ball of yarns by advancing along the lower twisting disk are fed; the upper platform is positioned below the upper twisting disc; a winding element for winding the one or more yarns passing through the upper twisting disk on the bobbin; the lower fixing table is positioned above the lower twisting disc; and a second motor for transmitting drive to the winding element by axial magnetic coupling. The yarn twisting machine includes a first power transmission device for rotating an upper twist drum around an axis, the first power transmission device being in communication with a first motor or a second motor and with the upper twist drum.
According to this preferred embodiment of the invention, the winding element is a winding drum, as disclosed in WO2008036055, and it is connected to (so as to be above) the lower fixing station. The lower fixed stage is held stationary by means of another axial magnetic coupling without pivoting.
According to an embodiment of the invention, the rotation of the upper twisting disk is provided by a drive from the spindle. Thus, the pulley at the top end of the main shaft is associated with a pulley on the upper twisting disk drive shaft which extends vertically and is spaced from the main shaft. A further pulley at the top end of the upper twisting disk drive shaft is connected to a pulley attached to a yarn guide which is fixed to the upper twisting disk by means of a further pulley. Thus, drive from the spindle causes the upper twist disk to rotate.
According to an embodiment of the invention, the twisted yarn, before being introduced into the upper twisting disk, can pass through a reel located above the upper twisting disk and freely rotating along a vertical axis, in order to reduce its friction.
According to one embodiment of the invention, the bobbin is rotated by means of the drive provided by the second motor via the second drive means, and in this embodiment the winding element providing the yarn to be wound on the bobbin is a traverse device which is axially movable by means of the third drive means on a shaft rotatably housed on the upper and lower fixed tables. According to the preferred embodiment, in this configuration, one or more yarns are passed through a plurality of spools (e.g., ceramic) having surfaces with very low coefficients of friction at separate locations from the feed point to the winding element. Thus, the yarn is prevented from being rubbed in the axial and transverse directions.

Detailed Description
The working principle of the yarn twisting machine of the invention is substantially the same as that described in WO 2008036055. Namely, below the frame (30), a first motor (44) rotating the main shaft (41) is pivotably supported on the machine body, while a lower twisting disk connected thereto is driven by transmission through a first motor belt (49); and the second motor (32) transmits the drive to a winding drum (29) moving a bobbin (27) on which the twisted yarn (twisted yarn) is wound, through a second motor belt (48). The second motor (32) also transmits drive to a yarn feeder (35) connected to an upper platform (37) located at the top side of the yarn twisting machine.
The yarn (34) to be twisted, unwound from a plurality of bobbins (31), is fed to the hollow main shaft by exiting through a lower twisting disc yarn outlet opening (55) in a carrying disc (81) located below the lower twisting disc (56) and is transferred into the machine through an upper twisting disc top opening (3) located at the top of the machine.
A lower stationary magnet ring (66) is provided which is fixed to the body coaxially with the main shaft (41), and a plurality of lower stationary magnets (46) are provided therein in an annular manner. A lower drive ring (79) is provided that is coaxially disposed with the main shaft (41), is configured to rotate independently of the main shaft by means of a rotational support, and to which a plurality of lower rotational magnets (47) are provided in an annular manner.
A carrier plate (81) is provided which rotates coaxially with the main shaft (41). The carrier plate is disposed above the lower stationary magnet (46) and the lower rotating magnet (47). The carrier tray (81) is made of a composite material, preferably having no electrical conductivity and no magnetic properties.
An upper drive ring (80) is provided, which is configured to rotate independently of the spindle by means of a rotatable support and is configured coaxially with the spindle (41) above the carrier disc (81). The upper drive ring (80) contains a plurality of upper rotating magnets (44) disposed therein in an annular manner. The upper drive ring (80) is rotatable by a magnetic coupling formed between an upper rotary magnet (44) and a lower rotary magnet (47) of opposite polarity provided in a lower drive ring (79) driven by a second motor (32) through a belt (48).
An upper fixed magnetic ring (82) fixed on the body and coaxially arranged on the main shaft (41) is arranged above the bearing disc (81). The upper stationary magnet ring (82) is provided with a plurality of upper stationary magnets (45) in an annular manner inside. The upper stationary ring (82) is immovable when the lower stationary magnet (46) and the opposite polarity upper stationary magnet (45) are aligned with each other and the lower stationary magnet ring (66) is fixed to the body. Since the upper stationary magnetic ring (82) is fixed to the lower stationary table (83) supporting the winding drum (29), it can be rendered immovable as well.
At the top end of the main shaft (41) is provided an upper twist disk drive lower pulley (10) which transmits motion from the main shaft (41) through an upper twist disk drive lower belt (11) to an upper twist disk drive shaft lower pulley (13). The upper twisting disk drive shaft (14) is rotatably supported at its lower end by an upper twisting disk shaft lower housing (12) arranged at the lower stationary stage (83) and at its upper end by an upper twisting disk drive shaft upper housing (15) arranged at the upper platform (37). The upper twisting disk drive shaft lower pulley (13) receives the upper twisting disk drive shaft (14).
An upper twisting disk driving shaft upper pulley (18) is arranged at the top end of the upper twisting disk driving shaft (14) and is connected with an upper twisting disk lower guide wheel (19) through an upper twisting disk driving upper belt (17). Thus, drive received from the upper twist disk drive lower pulley (10) is transmitted to the upper twist disk lower guide wheel (19). The upper twisting disk lower guide wheel (19) is rigidly attached to the upper twisting disk counter-center shaft (5) in a coaxial manner. The upper twisting disk central axis (5) is supported on an upper twisting disk axis centering bearing frame (6) which is fixed to the upper platform (37) by means of a rotatable support. An upper twisting disk cover (2) extends coaxially on top of the upper twisting disk to the middle shaft (5) and a central part of the upper twisting disk (1) is arranged between the upper twisting disk and the upper twisting disk. The upper twisting disk cover (2), the upper twisting disk (1) and the upper twisting disk pair central axis (5) are attached to each other by means of connecting means, such as vertically extending bolts. Thus, the upper twisting disk (1) can be rotated by means of the motion received from the upper twisting disk drive lower pulley (10). As shown in fig. 3, a lower tension pulley (21) and an upper tension pulley (20) may be used to adjust the tension of the upper twist disk driven lower belt (11) and the upper twist disk driven upper belt (17), respectively.
There are various ways to rotate the upper twisting disk (1). For example, drive may be provided from the main shaft (41) such that the upper twisting disk drive pulley (10) will be below the lower fixed table (83). In this case, the upper twisting disc drive shaft (14) may extend below the lower fixed table (83). In another embodiment, the required drive can be received from the second motor (32) by winding the upper twist disk drive lower belt (11) around the upper drive ring (80). According to another embodiment, the drive may be provided from the top close to the upper twist disk (1) of the yarn feeder drive shaft (36) to be described below. In any case, the pulley drive for rotating the upper twist disk (1) at the appropriate speed can be dimensioned in any preferred manner.
Although the working principle of the yarn feeder (35) is basically as disclosed in WO2008036055, the position of said yarn feeder (35) has been changed and it is moved to the lower part of the upper platform (37) when the upper twisting disk (1) is rotated. Since the yarn balls are relatively reduced and less yarn mass is turned, the loss of energy required by the machine is reduced. The upper drive ring (80) rotated by the second motor (32) transmits its motion through the yarn feeder lower belt (42) to the yarn feeder lower intermediate pulley (78), from where it is then further transmitted to the yarn feeder drive shaft lower pulley (43) by means of the yarn feeder drive shaft lower belt (9). A yarn feeder drive shaft lower pulley (43) is attached to the yarn feeder drive shaft (36) from below. The yarn feeder drive shaft (36) is supported from below by a rotatable yarn feeder drive shaft lower support (16) at a lower stationary table (83) and from above by a rotatable yarn feeder drive shaft upper support (8) in an upper platform (37). At the top of the yarn feeder drive shaft (36) is a yarn feeder drive shaft upper pulley (38) to which a yarn feeder drive shaft upper belt (39) is attached to a yarn feeder pulley (40). A shaft extending downward from the middle of the yarn feeder pulley (40) is connected to the center of the cylindrical yarn feeder (35). Thus, the rotary motion from the upper drive ring (80) is transmitted to the yarn feeder (35).
As shown in fig. 1, the twisted yarn (28) passing through the upper twisting disk top opening hole (3) extends downward from the opening formed between the upper twisting disk cover (2) and the yarn lower guide (5); introducing it (twisted yarn) into a yarn feeder (35) by winding it around an upper platform reel (7); and from there it is transferred to a winding drum (29) with a number of yarn guides by passing from a plait section (4) attached to the lower part of the upper platform (37). Since the winding drum (29) is in physical contact with the bobbin (27), the winding drum rotates the bobbin (27) while rotating, and thereby winds the twisted yarn on the bobbin.
As shown in fig. 4 to 7, a reel, such as a "propeller", which can freely rotate is provided on the top of the opening (3) at the top of the upper twisting plate. The propeller-type spool (24) is supported in a spool case (26) so as to rotate about its own axis, and the spool case (26) is supported by means of a rotation pin (22) provided in an upper twisting disk top opening (3). There is a propeller-type yarn guide (23) which is in contact with a spool housing (26) extending a distance from a propeller-type spool (24). As can be seen in fig. 6 and 7, the twisted yarn (28) advancing by contacting the edge of the upper twisting disk is wound on the propeller spool (24) after passing through the propeller yarn guide (23) and from there passes through the upper twisting disk top opening (3). Yarn friction across the top opening (3) of the twist-up disc is minimized by the free rotation of the propeller spool (24) along the vertical axis.
In fig. 8, a perspective view of a yarn twisting machine including another embodiment of the present invention is shown. According to this embodiment, both the cross-direction and the axial yarn friction will be further reduced. In this embodiment, preferably no yarn feeder is used and the twisted yarn is wound on the driven bobbin by means of a thread guide device.
The twisted yarn (28) exiting through the lower twisting disk outlet opening (55) is transferred to the upper twisting disk side spool (52) provided at the periphery of the upper twisting disk (1) by passing through the twisting disk spool (51) provided at the periphery of the lower twisting disk (56), and then to the upper twisting disk upper spool (53) provided at the top of the upper twisting disk top opening (3). The twisted yarn (28) exiting through the leading lower opening (25) passes through another reel (not shown in the figures) and is also fed to the thread-guiding device (74) by passing through the upper platform reel (54). The twisted yarn (28) is then passed through a plurality of spools on a guide (74) and wound onto a bobbin (27).
In fig. 9, a cross-sectional view of the spool drive structure is shown. The drive received by the second motor from the lower drive ring (79) through magnetic coupling is transmitted to the upper drive ring (80), and then transmitted to the bobbin rotation lower pulley (63) rotatably supported by means of the lower pulley support (64) through the bobbin rotation upper belt (65). The bobbin rotating belt (62) connected to the other end (upper end) of the bobbin rotating lower pulley (63) also transmits drive to the bobbin rotating pulley (61) disposed spaced apart from the bobbin rotating lower pulley (63).
A bobbin fixing lower piece (60) fixed to a bobbin rotating pulley (61) is fitted to an axial opening of the bobbin (27) so as to be attached thereto. Thus, the rotational movement received from the spool rotating pulley (61) is transmitted to the spool (27). The bobbin (27) is rotatably supported from the other end (from the upper part according to the figure) to the upper platform (37). For this purpose, a bobbin-fixing lever (57) fixed to the upper platform (37) and extending downward therefrom is provided. The bobbin fixing lever (57) is supported by a rotary bobbin fixing upper bearing (58) provided in an opening in a bobbin fixing upper member (59).
According to an embodiment of the invention, the bobbin winding rate may be controlled by an encoder (50). Accordingly, one or more yarns to be twisted, which are fed below the main shaft (41), pass through an encoder (50). Such control is provided, inter alia, to reduce the speed of the bobbin while increasing the amount of twisted yarn thereon. Necessary motor control is provided by feeding data on the amount of yarn delivered per unit time supplied from the encoder to the second motor drive circuit.
In fig. 10, a cross-sectional view of the upper deck lid driving structure is shown. In this embodiment, the drive mechanism for the upper deck lid is substantially the same as that shown in fig. 2. That is, the upper twist disk drive lower pulley (10) at the top end of the main shaft (41) transmits its drive through the upper twist disk drive lower belt (11) to the upper twist disk drive shaft lower pulley (13). An upper twist disk drive shaft lower support (13) is engaged from above to an upper twist disk drive shaft (14) supported in an upper platform (37) by rotating an upper twist disk drive shaft upper housing (15); and is engaged to the lower fixed table (83) by rotating the upper twisting disk shaft lower support (12) from below the main shaft (41). An upper twisting disk driving shaft upper pulley (18) at the top end of the upper twisting disk driving shaft (14) is connected with an upper twisting disk lower guide wheel (19) through an upper twisting disk driving upper belt (17). Thus, the drive received from the upper twist disk drive lower pulley (10) is transmitted all the way to the upper twist disk lower guide pulley (19). The upper twisting disk lower guide wheel (19) is rigidly attached to the upper twisting disk counter-center shaft (5) in a coaxial manner. An upper twisting disk cover (2) coaxially extending to the top of the middle shaft (5) is provided on the upper twisting disk, and the central part of the upper twisting disk (1) is fixed therebetween. The upper twisting disk cover (2), the upper twisting disk (1) and the yarn lower guide (5) are fixed with each other. Thus, the upper twist rotor (1) can be rotated by means of drive received from the upper twist rotor drive lower pulley (10).
In fig. 11, a drive system of a thread guide device for feeding a twisted yarn to a bobbin is shown. Drive received from an upper drive ring (80) is transmitted through a spool rotating upper belt (65) to a wire pulley (68) disposed below a wire guide shaft (76) which extends vertically and is spaced apart from the main shaft (41), and thus the wire guide shaft (76) can be rotated. The lead shaft (76) is supported to a lower fixing table (83) by rotating the lead shaft lower case (69). Similarly, the wire guide shaft (76) is supported to the upper platform (37) by rotating the wire guide shaft upper support (77).
A wire guide (74), as is known in the art, is provided to the wire guide shaft (76), the wire guide (74) moving up and down along its axis. An upper support (75) and a lower support (73) are provided in the lead structure (74), both supported to the lead shaft. The supports are in contact with each other by means of a connecting bracket (67). The supports are also connected by a reversing lever (72) having a circular extension extending outwardly from the wire guide (74) and passing through a pivot pin such that the axis of the supports changes when a sufficient force is applied to the circular extension of the reversing lever (72) from above or below.
Between the lower fixing table (83) and the upper platform (37), an upper limit portion (71) and a lower limit portion (70) are provided to a trunk portion (84) extending adjacent to the lead shaft (76). During operation, because the wire guide shaft (76) always rotates in the same direction, and because the axes of the lower support (73) and the upper support (75) do not coincide with the axis of the wire guide shaft (76), the wire guide device performs a linear motion on the shaft while the wire guide shaft rotates. This linear movement is maintained until the moment when the circular extension of the reversing lever (72) hits the lower limit (70) or the upper limit (71). When a collision occurs, the axis of the bearing turns in the opposite direction with respect to the axis of the wire guide shaft, and in this case, the direction of movement of the wire guide structure is reversed. Thereby, the twisted yarn received from the reel on the wire structure (74) is wound on the bobbin.
